3、接口复用说明

· BT1120:将 GMAC1 相关引脚用于 BT1120,则能实现 BT1120 相关输出(目前底板上没有留BT1120接口)。

· PCIE:目前有 1x 2Lanes PCIe3.0 Connector (RC Mode),如果想增加 PCIE2.0,将MULTI_PHY2配置为 PCIE模式。

· SATA:目前有1x SATA3.0,也可以通过配置 MULTI_PHY0、MULTI_PHY1为 SATA,就能实现3x SATA3.0。

· RGMII:目前有2x RGMII,如果想增加QSGMII,需要将MULTI_PHY1、MULTI_PHY2 配置为QSGMII。

六、搭建开发环境

1、安装依赖工具

安装命令如下:

sudo apt-get update && sudo apt-get install binutils git git-lfs gnupg flex bison gperf build-essential zip curl zlib1g-dev gcc-multilib g++-multilib libc6-dev-i386 lib32ncurses5-dev x11proto-core-dev libx11-dev lib32z1-dev ccache libgl1-mesa-dev libxml2-utils xsltproc unzip m4 bc gnutls-bin python3.8 python3-pip ruby

说明: 以上安装命令适用于Ubuntu18.04,其他版本请根据安装包名称采用对应的安装命令。

2、获取标准系统源码

前提条件

1)注册码云gitee账号。

2)注册码云SSH公钥,请参考码云帮助中心

3)安装git客户端git-lfs并配置用户信息。

git config --global user.name "yourname"

git config --global user.email "your-email-address"

git config --global credential.helper store

4)安装码云repo工具,可以执行如下命令。

curl -s https://gitee.com/oschina/repo/raw/fork_flow/repo-py3 > /usr/local/bin/repo #如果没有权限,可下载至其他目录,并将其配置到环境变量中

chmod a+x /usr/local/bin/repo

pip3 install -i https://repo.huaweicloud.com/repository/pypi/simple requests

获取源码操作步骤

1) 通过repo + ssh 下载(需注册公钥,请参考码云帮助中心)。

repo init -u git@gitee.com:openharmony/manifest.git -b master --no-repo-verify

repo sync -c

repo forall -c 'git lfs pull'

2) 通过repo + https 下载。

repo init -u https://gitee.com/openharmony/manifest.git -b master --no-repo-verify

repo sync -c

repo forall -c 'git lfs pull'

执行prebuilts

在源码根目录下执行脚本,安装编译器及二进制工具。

bash build/prebuilts_download.sh

下载的prebuilts二进制默认存放在与OpenHarmony同目录下的OpenHarmony_2.0_canary_prebuilts下。

七、编译调试

1、编译

在Linux环境进行如下操作:

1) 进入源码根目录,执行如下命令进行版本编译。

./build.sh --product-name rk3568 –ccache

2) 检查编译结果。编译完成后,log中显示如下:

post_process

=====build rk3568 successful.

2021-09-13 09:22:28

编译所生成的文件都归档在out/ohos-arm-release/目录下,结果镜像输出在 out/ohos-arm-release/packages/phone/images/ 目录下。

3) 编译源码完成,请进行镜像烧录。

2、烧录工具

烧写工具下载及使用。
